121445 divided by 53 
The aim is to understand the frequency of 53 in 121445.

Moving on to step 1:
53 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 53

Step 2:
If we divide 12 by 53, we get 0 and a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Append the next digit (1) from the dividend to 12 and continue with: 121 / 53

Step 3:
When dividing 121 by 53, we get 2 with a remainder of 15.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 106 from 121 and we're left with 15.
Include the next digit (4) from the dividend after 15, then repeat: 154 / 53

Advancing to step 4:
The number 53 fits into 154 2 times, leaving a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 22.0
If we subtract 106 from 154, we get 48.
Include the next digit (4) from the dividend after 48, then repeat: 484 / 53

Advancing to step 5:
If we divide 484 by 53, we get 9 and a remainder of 7.
The next digit of our result is 9. 
Result so far: 229.0
Subtract 477 from 484 to get 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 53

Advancing to step 6:
The number 53 fits into 75 1 times, leaving a remainder of 22.
The number 1 becomes the next digit in our result. 
Result so far: 2291.0
Subtracting 53 from 75 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 7:
When dividing 220 by 53, we get 4 with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 2291.4
Subtract 212 from 220 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 8:
The number 53 fits into 80 1 times, leaving a remainder of 27.
Write down 1 as next digit of the result. 
Result so far: 2291.41
Subtracting 53 from 80 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 9:
When dividing 270 by 53, we get 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 2291.415
The remainder is 5 after subtracting 265 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 10:
50 divided by 53 is 0 with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 2291.415
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 11:
53 goes into 500 9 times with a remainder of 23.
The next digit of our result is 9. 
Result so far: 2291.41509
Subtract 477 from 500 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 12:
53 can be fit into 230 4 times, resulting in a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 2291.415094
Subtract 212 from 230 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 13:
53 can be fit into 180 3 times, resulting in a remainder of 21.
The next digit of our result is 3. 
Result so far: 2291.4150943
Subtract 159 from 180 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 14:
The number 53 fits into 210 3 times, leaving a remainder of 51.
Record the quotient 3 as the next digit in the result. 
Result so far: 2291.41509433
Subtracting 159 from 210 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

The quotient of the division is 2291.41509433, and the remainder is 5.1e-08.
